2005 Rust

[topo4u2]

Alright, I know about the campaign for the rust around the air holes on the front bumper but just took the truck in for a wash and as I was doing the rear bumper I noticed a small spot of rust on the centre of the rear bumper....mind you its very small...about the size of a head of a needle but its there. Anyone seen this on there trucks 05? I guess I better have the body shop at the dealer take a peak at it anyway. Truck has 41000km on her.

 

I think its time for some new bumpers!

Could you elaborate on the campaign for rust in the air holes? I noticed that too on my Sierra...thanks!

If you search this site you may find the write up on the campaign but here is the number for it. #03-08-62-003B - May 12, 2005. I have not taken mine in for this yet....may wait till spring but Im going to show them the rust on the rear bumper this week when it goes in for an oil change.

I am not happy to read about this. Do '06 trucks have the same problem? I had a '95 Nissan pickup with chrome bumpers and when I traded it in last month it did not have a spec of rust on either bumper. After 10 years in humid coastal Florida!

 

How hard is it to make a decent chrome bumper given today's technology?

I had my rear bumper replaced on my '01 because of rust.

 

I noticed small spots trying to show through the chrome. They would easily rub out, but for about 6 months I just let them go so I could show my dealer. They replaced it with no questions asked.

Well, I'm happy to say my '88's front bumper still looks like new (and the step bumper has new paint) LOL.

No rust on my '05's bumpers. The inside of the bumpers have a black coating. I just crawled underneath to look. I'm in a salty area as well, due to the boat launches.

 

If you have rusty bumpers, not caused by a ding penetrating the chrome and exposing the metal, I'd take the truck in and complain. And for what it is worth, these are very light-duty bumpers. Extremely light duty. Don't let the shiny bling bling chrome fool you.

Though it is light duty, my '95 bumpers held out exceptionally. I did see some peeling at the back side, but the exposed front areas held up very well through 10 years of Canadian weather. Given the ways things are made these days, especially bumpers, I'm not surprised how flimpsy the gauge of metal used to their chroming process is performed. I'll be paying closer attention to my bumpers over this Winter for sure!

Nothing is the same as it was a few years ago in metal finishing. The "Chrome" you are looking at is probably from a tri-valent chrome bath or a substitute plating and not the good 'ol Hex Chrome from the good ol days past.

 

Chrome plating is a very expensive process and much occurs long before the parts are even plated with the chrome. The parts would be copper plated and polished and nickel plated first.

 

The Governments of the WORLD (rightly) are really getting down on certain types of plating, chrome is #1 on the hit list. This is because Hex Chrome is a terrible poison and can contaminate land/water for decades, cause cancers and other horrible problems. Most mfg's have/are swithing to other types of plating that looks similar but DOES NOT offer the corrosion resistance like good ol chrome.

 

Yes, plating is very difficult. The technology is ancient, even in today's world.

I am a QE in the metal finishing Industry.

That's like the banning of using a Chrome Yellow color for our police cars back in the late 70's over concerns of health issues of the material used. Soon these bumpers will be chome plated with a process similar to that of plastic model kits!

[pm26]

Metals really corrode at an amazing rate here in coastal Central Florida (Cocoa Beach area). US Army actually tested their metal truck parts for corrosion resistance in this area (on Cape Canaveral beach to be exact). Believe it or not, even chromed plastics corrode around here. The way I understand it, before plastics are chromed, they are plated with a thin layer of some metal, and it is the metal underneath that corrodes, giving appearance of corroded chrome on plastic.

Since we're on the bad four letter word - rust - has anyone seen products that stops the rusting process on the vehicle and redirects them to "pads" affixed to the body and runs on 12v? The outcome is that these "pads" or anodes, attract the negative ions (that cause rust) and attacks the pads/anodes, thereby sparing the sheet metal. As these pads/anodes wear out, they simply get replaced. They suppose to be popular with large ships that are steel/iron cladded.

[trever1t]

Yes, this technology is old and used most often on metal boats and such. Electrolysis (sp) is worse than rust! Sacrificial anodes or as you mention, and i forget the name of the device, will prevent metals from leaving your boat and ending up on somthing else!

[slemmer]

I wasn't aware of the eletrolysis part. (Chemistry wasn't my strong point) It's probably why it isn't (widely) used in the automotive industry.

It's all about cutting corners to save a little more $$$, as a result, we the consumers get screwed.
